Hybrid Matrix Composites

A hybrid matrix composite combines more than two kinds of matrixes, like a metal and a polymer.

In a polymer metal sandwich construction the matrix is formed by metal sheets and a polymer honeycomb structure which is fiber reinforced.

Polymer Metal Sandwich Sheet composites are made from a polymer honeycomb structure enclosed by two thin metallic sheets. A resin or adhesive is used as a matrix and holds it all together. The honeycom structure makes the composite relatively light, but stiff. An example of a Polymer Metal Sandwich Sheet is Hylite which is made of two thin aluminium layers with a plastic (polypropylene/PP) core in between.
